' SPECIFICATION forming part of Letters Patent No. 435,006, dated August26, 1890.

" Application filed April'7, 1890. Serial No. 346,394. (No model.)

To all whom it may concern.-

Be it known that I, EDGAR W. ANTHONY, of Brookline, in the county ofNorfolk and State of Massachusetts, a citizen of the United States, haveinvented a new and useful Improvement in Ranges, of which the followingis a full, clear, and exact description, reference being had to theaccompanying drawings, forming a part of this specification, inexplaining its nature.

The invention relates to that class of ranges known as whole-sheet-fiueranges -that is, a range in which the products of combustion and heatpass over the oven down one side underneath the oven to an uptake uponthe back of the range. In order that the products of combustion and heatmay not pass directly from the lower end of the downtake, as it iscalled, directly to the uptake upon the back, and thereby not properlyheat the bottom of the oven, there has been arranged across the cavitybelow the oven which forms the flue a partition extending from the backwall of the range partially across the cavity or space to cause theproducts of combustion to pass between its front end and the front wallof the space. lVhile this efiects a better circulation of the productsof combustion and heat as they pass through this portion of the line tothe uptake, still it causes a draft or circulation of such a nature thatcertain portions of the oven-bottom are not properly heatednamely, theportion where the partition-plate joins the rear wall and the portion atthe corner immediately beyond the uptake. To obtain a better draft orcirculation and distribute it so that the bottom of the oven shall beuniformly heated in all parts, I have provided the flue or cavity belowthe oven-bottom plate with a bridgepartition-that is, a partition whichextends from the back wall of the range, preferably, though notnecessarily, diagonally across the cavity to, or very nearly to, thefront plate, and which plate is provided with openings, preferably,though not necessarily, graduated as to area or size, as hereinafterspecified. I also arrange the uptake so that it extends from the rearback corner of the stove along the back of the stove any requireddistance, preferably to the end of the flue-plate, while at the sametime I make it narrower than it from the side to the end of thepartition plate, and may be of the same degree or extent throughout thelength of the opening to the uptake.

Referring to the drawings, Figure 1 1s a view in perspective of a rangecontainlng my improvement, portions of the range being broken. out tobetter illustrate the invention. Fig. 2 is a view in section thereoffrom side to side. Fig. 3 is a view in plan thereof below the bottomplate of the oven. Fig. 41s a view in plan below the bottom plate of theoven, representing the flue-plate as occupylng a different position fromthat represented n Fig. 3. Fig. 5 is a view of a flue-plate n which theopenings are of the same area. Flg. 6 represents a flue-plate made of anumber of independent sections attached to the bottom plate of thestove. Fig. 7 is a flue-plate representing the equivalent of openings ofdifferent areas obtained by a long opening varying as to width from oneend to the other of the plate.

A represents the oven of a range; a, the fire-pot; a, one side of therange; a the other side; a the front, and ct the back. The products ofcombustion pass from the fire-pota over the top plate Z) of the oven,between it and the top plate B of the range, and of the full width ofthe range from front to back. They then pass downward by the side plateI) of the oven through the downtake b between the said side plate andthe side plate 19 of the range, and of the full width of the range fromback to front. or chamber b below the bottom plate b of the oven andbetween it and the bottom plate I) of the range. Thence upward throughthe uptake 0 between the back plate cof the oven and theupwardly-extending section a of the back wall of the range. The lowercavity or chamber 12 has extending across it a partition or flue plateD. This plate extends from the back plate 0 of the range entirely acrossor almost entirely across the cavity or chamher. It may extend acrossthe same diagonally, as represented in Figs. 1 and 3, or it may extendacross the same at a right angle Thence into the cavityto the back, asrepresented in Fig. 4. I much prefer the first-named arrangement. In theplate D there are formed openings (1. These openings may be of the samearea as represented in Fig. 5, or they may be of different areas, asrepresented in Fig. 7. I prefer the last-named arrangement, and alsothat they be so graduated that the opening of the smallest area shall benearest the back plate 0 and the opening of largest area nearest thefront plate and the intermediate openings graduated regularly from thesmallest to the largest. A circulation or draft from one fine to anotheris almost invariably by the shortest route; but if the circulation isretarded or prevented from taking this shorter course it must ofnecessity take the longer course, and in my present invention I haveadjusted the relative size of the openings in the partitionplate so thata sufficient retardation takes place from one end of the plate to theother to cause the circulation or the products of combustion to seek orbe drawn through all the openings bf the plate in order to reach theuptake, and the increased area of the more remote or indirect openingscompensating for the smaller and more direct openings. I facilitate thisaction of the circulation by the shape of the uptake. This hasheretofore been comparatively short from side to side and wide fromfront to back, and I have widened it at its point of connection with thecavity or chamber, and narrowed it so that it extends from the corner 0or intersection of the front plate 19 of the oven with the rear plate aof the range, to the point 0 close or adjacent to the point where thepartitionplate D joins the rear plate 0, and I have contracted ornarrowed the space between the rear plate 0 of the oven and the parallelportion of the section a. By this means an opening of practically theentire side or end of that portion of the chamber or cavity below thebottom plate of the oven and in front of the partition-plate into theuptake is obtained, and no (lead-air space or space not open to thecirculation is provided, as in other constructions. Of course thepartition-plate D may not be in one piece throughout, as the openingsmay be formed by separatepieces or sections fastened to one or the otherof the two plates b b. In lieu of a bridge partitionplate havingseparate openingsythe same effect may be obtained by making abridgeplate with a continuous openingincreasing in height from'the rearend of the plate to the front end, so that the area of the openingincreases in size from. the rear to thefront end of the plate, and theretardation of the circulation decreases from the rear to the front,(see Fig. 7,) where such plate is shown.

In use the products of combustion pass over the top plate I) of the ovenin a wide thin body, then downward at the side of the side plate Z),then through the chamber Z9 in a wide body, which is maintainedthroughout the chamber or cavity and about the turn to the uptake,because of the retarding, guiding, and directing character of the bridgepartition-plate, and this insures a uniform heating of the entire bottomplate 6 of the oven at all points, which is a very desirable result toobtain.

Having thus fully described my invention, I claim and desire to secureby Letters Patentof the United States- 1. In a whole-sheet-fiue range, apartition or flue-plate arranged in the time cavity or space below thebottom plate of the oven, having a graduated opening or openings thereinincreasing in size or area from the point where the circulation or draftis stronger, as and for the purposes described.

2. The combination, in a whole-sheet-flue range, of the downtake b theflue chamberor cavity 19 below the bottom plate of the oven, the uptake0, and a partition or fine plate D, extending diagonally across theflue-chamber b and having one or more openings which are enlarged orhave greater area as the plate recedes from the down and up take, as andfor the purposes described.

- 3. In a stove or range, an uptake 0 upon the back, connected at itslower end with the flue chamber or cavity below the bottom plate of theeven by a long and narrow opening extending from the corner formed bythe meeting of the front and back plates of the flue-chamber to ornearly to the point atwhich the partition-plate extends from the backplate across said flue chamber-or cavity, in combination with saidpartition-plate, as and for the purposes described.
